Round your answers below to 2 decimal places. a. What is the opportunity cost of producing one bushel of wheat in Richland? 1 bushel of wheat = 0.33 barrels of wine. b. What is the opportunity cost of producing one barrel of wine in Richland? 1 barrel of wine = 3 bushels of wheat. c. What is the opportunity cost of producing one bushel of wheat in Prosperity? 1 bushel of wheat = 1.5 barrels of wine. d. What is the opportunity cost of producing one barrel of wine in Prosperity? 1 barrel of wine = 0.67 bushels of wheat. e. In what product does Richland have a comparative advantage? Richland: Wheat f. In what product does Prosperity have a comparative advantage? Prosperity: Wine Suppose that both countries are presently producing combination C. g. Fill in the blanks in the following table: TOTAL OUTPUT IN MILLIONS OF UNITS Wheat Wine Richland 30 10 Prosperity 20 30 Total Both countries 50 40 Now suppose that each country specializes in the product in which it has a comparative advantage. h. Show the results in the following table: Wheat Wine Richland 60 0 Prosperity 0 60 Total Both countries 60 60 i. What is the joint gain from trade? 10 Wheat and 20 Wine Suppose that the two countries establish the terms of trade at 1 wine = 1.5 wheat, and Prosperity decides to export 18 wine to Richland. j. In the following table show how the two countries will share the gains from trade. Round your answers below to 1 decimal place.

Suppose any four workers (selected randomly) in Kenya can together, produce either 2 cars or15 tons of coffee in a year. If Kenya’s total resource available is 10 million equally efficientworkers, (decimal quantities of the resource and the two goods are possible)(a) calculate the opportunity cost of producing one car in Kenya, in a year? [4 marks](b) calculate the opportunity cost of producing one ton of coffee in Kenya, in a year? [4 marks]

Consider Home and Foreign in a Ricardian world (includes all the assumptions of the Ricardianmodel). Each country produces two goods, wine and cotton. Each country has 4,800 labour hoursavailable. The accompanying table shows the number of hours required to produce one unit ofeach good in each country. Answer the following questions using the information given by thetable:a. What is the opportunity cost of cotton in each country? Show your work.b. Draw the graph of the production possibility frontier (PPF).c. Which country has an absolute advantage in Wine? Explain your answer.d. Which country has a comparative advantage in Wine? Show your work and explain your answer.e. Which good does each country produce and export when the equilibrium international relativeprice of wine in terms of cotton is 1?f. Suppose the equilibrium international relative price of wine in terms of cotton is 1. Draw the graphof the production possibility frontier (PPF) for each country when they trade. Show how the twocountries can benefit from free trade. Explain your answer and fully label your graph to get marks.g. Draw the world relative supply (RS) of wine. Fully label your graph to get marks (Do not drawthe world relative demand (RD) of wine yet).h. Now, suppose that the world relative demand is drawn such that the equilibrium internationalrelative price of wine is at 1. Draw the world relative demand curve of wine on the diagram above(in part g). Explain which country (countries) benefit(s) (most) from free trade in this case.i. Now, suppose that the world relative demand is drawn such that the equilibrium internationalrelative price of wine is at 1.25 (=5/4). Draw the world relative demand curve of wine on thediagram above (in part g). Explain which country (countries) benefit(s) (most) from free trade inthis case.j. Calculate Home country’s relative productivity of labour in each sector.k. Suppose that the price of wine is $10 per bottle and the price of cotton is $10 per bushel. Calculatethe relative wage in Home (the wage of Home relative to the wage in Foreign). Show your workand explain your answer.l. Show the relative wage in Home lies in between the relative productivity of labour of two sectorsusing the information you obtained from parts j and k.Wine CottonHome 6 8Foreign 5 4
